Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of belt conveyer relates to a tension device for belt conveyer. BACKGROUND

[0002] The belt conveyer, also known as a conveyor belt, is a widely used material conveying equipment, mainly used for continuously and stably conveying various materials. The belt is usually made of rubber or synthetic material, but long-term use can cause the belt to relax due to factors such as material fatigue, friction loss, thermal expansion and contraction, and overloading capacity. Then the tension device is needed to tighten the belt. The current existing tensioning method is to move the drive roller position to tighten the conveyor belt. This method has a complex structure and high cost. The existing utility model patent No. 2024200467145 provides an automatic tensioning wheel tensioning device for belt conveyer. When in use, part of the conveyor belt is twisted into an S shape to tighten the conveyor belt. However, the degree of twisting of the conveyor belt is large, which increases the friction of the conveyor belt after being twisted into an S shape, and even affects the normal operation of the conveyor belt, resulting in poor use effect. CONTENT OF THE UTILITY MODEL

[0003] The utility model aims at the problem of poor use effect of the existing conveyor belt tensioning device in the background art, and provides a tension device for belt conveyer.

[0004] Therefore, the utility model adopts the following technical scheme:

[0005] A tension device for belt conveyer, comprising a conveyor belt, the conveyor belt comprising an upper belt and a lower belt, a support being provided below the conveyor belt, a first support roller and a second support roller being provided on the support along the width direction of the conveyor belt, the first support roller and the second support roller being located between the upper belt and the lower belt and abutting against the upper side of the lower belt, a tension roller being provided on the support along the width direction of the conveyor belt and being movable up and down in the vertical direction, the tension roller being located between the first support roller and the second support roller and abutting against the bottom of the lower belt. Further, the first support roller is arranged horizontally.

[0006] Further, the first support roller and the second support roller are arranged in parallel and located in the same horizontal plane.

[0007] Further, the tension roller is arranged in parallel with the first support roller.

[0008] Further, a jack is provided on the support, a support rod being provided at the top end of the jack and arranged vertically, a mounting bracket being provided on the support rod and having a U-shaped structure, and the tension roller being mounted on the mounting bracket.

[0009] The utility model discloses beneficial effect lies in: set up the first support roller and the second support roller, and the outside force is exerted to the lower side band of conveyer belt through the first support roller and the second support roller, and the conveyer belt is taut through the cooperation of the first support roller and the second support roller, and the use effect is good. BRIEF DESCRIPTION OF DRAWINGS

[0010] Figure 1 It is the structural schematic diagram of the utility model;

[0011] Figure 2 It is Figure 1 The sectional view of A-A direction in middle;

[0012] In the drawing, 1-conveyer belt, 101-upper side band, 102-lower side band, 2-bracket, 3-first support roller, 4-second support roller, 5-tensioning roller, 6-jack, 7-supporting rod, 8-mounting frame. DETAILED DESCRIPTION

[0013] The utility model will be described in detail below in combination with the drawings:

[0014] As Figure 1 And 2 As shown in a kind of tensioning device for belt conveyor, including conveyer belt 1, conveyer belt 1 includes upper side band 101 and lower side band 102, the lower side of conveyer belt 1 is equipped with bracket 2, bracket 2 is equipped with first support roller 3 and second support roller 4 along the width direction of conveyer belt 1, first support roller 3 is horizontally arranged, and second support roller 4 is mutually parallel with first support roller 3 and is located in the same horizontal plane, first support roller 3 and second support roller 4 are located between upper side band 101 and lower side band 102 and abut on the upper side of lower side band 102, first support roller 3 and second support roller 4 can provide downward pressure to the lower side band 102 of conveyer belt 1, bracket 1 is equipped with tensioning roller 5 that can move up and down along vertical direction along the width direction of conveyer belt 1, tensioning roller 5 is arranged mutually parallel with first support roller 3, tensioning roller position 5 is located between first support roller 3 and second support roller 4, and tensioning roller 5 is on the bottom of lower side band 102, tensioning roller 5 can provide the pressure on the upper side of lower side band 102, first support roller 3, second support roller 4 and tensioning roller position 5 are arranged in triangle, specifically, bracket 2 is equipped with jack 6, jack 6 uses existing conventional shear type jack, and the cost is low, the top of jack 6 is equipped with the supporting rod 7 that is vertically arranged, jack 6 can drive supporting rod 7 to move up and down along vertical direction, supporting rod 7 is equipped with the mounting frame 8 of U-shaped structure, and tensioning roller 5 is installed on mounting frame 8.

[0015] The use mode of the utility model is as follows:

[0016] When the conveyor belt 1 becomes slack, the operator only needs to operate the forward pusher 6 to move the support rod 7 and the tension roller 5 upward. The tension roller 5 lifts the corresponding part of the lower side belt 1 of the conveyor belt 1. At the same time, under the action of the first support roller 3 and the second support roller 4, the corresponding part of the lower side belt 1 bulges upward, thereby achieving a tensioning effect. If the first support roller 3 and the second support roller 4 are not set, the tension roller 5 needs to move a large displacement upward to achieve the tensioning effect, which may cause the bottom of the lower side belt 102 to come into contact with the bottom of the upper side belt 101 and rub against each other, affecting normal use.

[0017] This device has a simple structure, is easy to use, provides good tensioning effect, and is inexpensive.
